ELECTRIC LOCOMOTIVE.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed December 9, 1919. Serial No. 343,656.

To all whom it may concern lie it known that I, CHAnLns C. Pownns, a citizen of the United States, residing at Kernville, in the county of Kern and State of California, have invented a new and Improved Electric Locomotive, of which the following is a specification.

My invention has reference to locomotives and articularly to electric locomotives,and has .or its purpose to provide an improved means for transmitting the power from the motor for actuating the side rods that con ncct with the driving wheels, which, in the usual construction. of locomotives are linked with and actuated by the steam shifted piston rod.

More specifically, my invention comprehends an. improved arrangement of transmission devices connected with and adapted for applying rotation to the driving wheels and so coupled with a single electric motor, so positioned, with respect to the driving wheels at each side of the engine, that the power of the said single motor may be transferredto the driving wheels in a manner resultant in the development of an effective traction effort, when running under ordinary or high speeds.

The drawing hereto annexed, illustrates diagrammatically a general arrangement of the parts constituting my improvement and in which:

Figure 1 represents in side elevation a locomotive equipped with my arrangement of motor driven power transmission connections that join with the driving wheels.

Fig. 2 is a plan. view of my invention.

In carrying out my invention, an electric motor 1 is suitably mounted within a cab 2 indicated in dotted lines on Fig. l. The motor shaft 1, at its projected end, carries a worm gear 3 which may he formed with or otherwise fixedly connected with the said. shaft.

The power transmission connections that join the motor or driving gear 3 with the engine drivers or wheels 4 (of which a numher are shown having the usual link connections 4M0) and which constitute the essential feature of my invention, comprise a driven shaft 5 that is journaled in any approved manner in suitable hearings (not shown), and which extend transversely, with res ect to the motor, as is best indicated in ig. 2, by reference to which it will he observed that the shaft 5, midway its length, has an allixed worm gear 6 that" meshes with the motor shaft worm gear 3.

the transmission devices, at each side, are constructed and operated. alike, relatively to their respective sets of driving wheels 4, a detailed description of one set of such connections will be suflicient for both.

7 designates a disk fixedly mounted on the outer end of the drive shaft 5 and 8 is a wrist or crank pin attached to the disk.

In my arrangement of transmission mechai'iism, the rotary motion of the disk 7 is transferred into a reciprocatory motion for impelling the slide rod 9, which acts as a substitute for the usual steam chest actuated piston rod and which, in my construction, is also pivotally joined to the outer or main driving wheel l.

By referring more particularly to Fig. 1, it will he noticed, the outer end of the rod 9 is pivotally joined to the lower end of, what might be termed a draw bar 10, since the motive power is transferred from it directly to the rod 9, the latter receiving its impelled motion from the bar 10, the same as if it were a tuated through connection with the usual steam chest.

The draw bar 10 includes a crankdike portion 11 and has a slotted upper end 12, the latter being connected to the crank wrist pin 8 on the disk 7.

At the angled portion, the bar 10 is rockably mounted on a fulcrum member or shaft 13 that extends crosswise of the framing, see Fig. 2.

From the foregoing description taken in connection with the drawing, the complete construction, the manner of its operation and the general advantages ofmy construction of electric locomotive will be apparent to those skilled in the art to which it apper tains.

Assuming the engine to be running and the disk. 7 as turning in the direction of the arrow thereon, the rotary disk motion develops the oscillatory motion to the draw bar 10 in the direction of the arrows thereon, and further assuming the crank portion of the said bar 10 to he now moving in the direction of the arrow as, the rod 9 would now be impelled in the direction of the arrow 1 and the links 40 being above the axes of the drivers 4 will he transmitting draw bar actuated through the rotation to the drivers in the direction indicated under the now forward thrust of the bar 9 until the links 40 pass the dead or horizontal centers of the drivers, when the rotation of the drivers is continued by the now backward pull or thrust of the bar 9.

What I claim is:

1. In a locomotive, an electric motor driven rotatable shaft, a transmission con necting the shaft and the driving Wheels, said transmission including an oscillatable rotary motion of the motor driven shaft, and a reciproeably operating bar that connects the oscillatable draw bar With one of the driving Wheels.

2. In a locomotive, a motor driven shaft, a transmission connecting the shaft and the driving wheels, said transmission including an oscillatable draw bar actuated through the rotary motion of the motor driven shaft,

and a reciprocably operating bar that connects the oscillatable draw bar with one of the driving wheels, the said oscillatable draw bar including a slotted upper end and a crank or wrist pin connection.

3. In a locomotive, a motor driven shaft, a transmission connecting the shaft and the driving wheels, said transmission including an oscillatable draw bar actuated through the rotary motion of the motor driven shaft, and a reciprocably operating bar that connects the oscillatable draw bar with one of the driving wheels, the said oscillatable draw ha r including a slotted upper end and a crank or wrist pin connection, the said transmission including a crank disk on the shaft, an osciilatable draw bar actuated by rotation of the said shaft, the said bar in cluding an upper slotted member that en gages the crank ofthe aforesaid disk and a lower crank shaped end, and a reciprocahly operating bar that pivotally connects at one end with the crank end of the draw bar and pivotally joins at its other end with one of the driving wheels.
